Right-sized logic fabric for instant-on control
The Lattice LCMXO3LF-9400E-5BG256I is a MachXO3 FPGA with 9400 logic cells and 206 user I/O — enough fabric to absorb a board's worth of discrete glue logic, bus bridging, and power-sequencing state machines without reaching for a larger SRAM-based FPGA that needs an external configuration memory. Instant-on, non-volatile configuration means this part is live at power-up with no boot delay — it replaces CPLDs and small FPGAs in applications where the I/O must be valid before the main processor finishes its reset sequence.
Logic density, I/O, and on-chip memory
1175 LABs/CLBs and 442368 total RAM bits give you room for a 32-bit wide FIFO, a few small look-up tables, and a handful of counter/timer blocks — the embedded RAM is sized for line buffers and register files, not frame buffers. 206 I/O in a 256-CABGA (14x14 mm) package — the ball pitch is 0.80 mm, which routes cleanly on a 4-layer board with standard via-in-pad rules.
Active production and compliance
It is ROHS3 compliant, so it passes the material declaration for EU and UKCA markets without an exemption claim. The base product number is LCMXO3 — the speed grade is -5 (standard), and the 'E' suffix indicates the low-power 1.2 V core option. The 'I' suffix is the industrial temperature range, which is the version most often specified for control and communications equipment.
Sourcing and availability
For a BOM hedge, the MachXO3 family includes pin-compatible variants with different logic densities and I/O counts — the 206-ball BGA footprint is shared across several density grades, so a board layout can accept a larger or smaller device if the supply situation shifts.
